Thank you so much for your insight! It's great to have somebody on board who understands the accounting intricacies related to fabless companies!
Do you mind if I ask a few questions?
- How do you define 'profit margin' ? According to Wikipedia: "It is difficult to accurately compare the net profit ratio for different entities. Individual businesses' operating and financing arrangements vary so much that different entities are bound to have different levels of expenditure, so that comparison of one with another can have little meaning." Can you clarify how Nvidia uses it between different entities?
- If we assume that 95% of the development/code between high-end and low end chips is shared, how do you spread opex between high and low end chips? You could arbitrarily assign everything to the high end product and nothing to the low end product or vice versa and dramatically change the profit margin for either product (I'm assuming you include R&D in this because otherwise 8% wouldn't make sense because of known 40%+ gross margins.)
- How do you take into account general GPU marketing efforts that don't explicitly target a particular high-end or low-end card?
- We know that the professional products and consumer products use the same silicon. How do you spread the opex between those to product lines? It only seems fair that you pro-rate them according to revenue, right? Or would you do it accourding to chip volume? In the former case, the consumer products are guaranteed to be much more profitable than AMD's products (who has no professional revenue to speak of and has to charge all opex to their consumer products). In the later case, you'd burden the high running consumer products with unused professional features.
- How does the gross margin factor into this whole story? How high do you think they are? Do you think Nvida ever buys a working die from TSMC and sells it for less than it cost to produce? (That would be intensely stupid, right?) If not, then they have positive gross margins and it would be beneficial to keep on selling their wares to generate additional cash. Can you call that 'selling for a profit', even if 1 or 2 years later, it turns out that earlier R&D investments where not fully recouped? If not, what would you call it?
I look forward to your expert opinion regarding these matters! Feel free to consult your
mentor first. (While you do so, can you also ask him to revise
an accounting related article he edited roughly a year ago? Looking back, it doesn't exactly seem to stand the test of time, especially the part where, based on a bogus opex premise, it states that they "gave up on this generation and has nothing new in its pipeline for the short term, so it is looking forward to the next chip generation".)
